I love Portal. 'Nuff said. Chell was originally an excuse to make a big plush Companion Cube, but then I decided to make her my Halloween costume.
The jumpsuit is made from a Kwik Sew coveralls pattern that I heavily modified. It still needs some fitting; the pattern is originally meant for big manly men, and I am not a big manly man.
Heel springs are made from craft foam + wire. They're kind of flimsy, I want to make better ones for when I wear Chell to a con.

Personal Thoughts:

I really love this costume, despite it needing a few tweaks. Can't wait to perfect it for Connecticon in the summer.Also, derpy dorm photos are derpy.
